Like some other people, I was very anxious to try this hair treatment and wasn't very positive about it working on my extremly curly hair with very tight ringlets. I thought that as the treatment was only £25,it was cheaper than any other salon treatment, I thought I should give it ago, but only after hours of careful research and hundreds of customer reviews read to make sure it wouldnt damage or harm my hair in anyway. I can honestly say this product has worked wonders on my hair. The 72 hours period after applying the product where you are not allowed to wash your hair or put it in a ponytail or anything, I found it quite difficult as I didnt want to leave the house and by the third day, my hair was pretty greasy. After washing my hair, I felt an immediate difference. My hair was silky soft and extremly smooth, so I was happy that my hair had such a quick and positive effect. I then dried my hair straight away to see if the product had the 'dry and go' effect. Sadly, the product did not make my hair dead straight like I had hoped, but it did have a fantastic effect! Only the tips are slighty wavy and instead of it taking over an hour to straighten my hair, it now only takes me no longer than 5 minutes to straighten the tips of my hair. I would highly recommend this product to anyone who spends a long time styling their hair. It dramatically cuts down the styling time of your hair. Also, if you have purchased this product but are having trouble looking for a cheap sodium chloride free shampoo, I would recommend TRESemme naturals shampoo and conditioner. It is a well known, cheap and accessible shampoo. I hope this helps anyone who is un-sure about buying this product.
